Abstract
Behçet disease (BD) is associated with endothelial dysfunction and chronic inflammation. The neutrophil–lymphocyte (N/L) ratio and carotid intima–media thickness (cIMT) are markers of inflammation and vascular risk, respectively. We assessed the relationship between cIMT values and N/L ratio in BD (65 patients and 62 control participants). There were statistically significant differences in N/L ratios and cIMT values between the patients with BD and control group ( P < .001). There were moderate positive correlations between cIMT value, C-reactive protein, and N/L ratio in patients with BD. Receiver–operating characteristic curve analysis suggested that the optimum N/L ratio cutoff point for patients with BD was 1.29, with a sensitivity, specificity, negative predictive value, and positive predictive value of 97, 77, 96, and 75%, respectively (area under curve: 0.691, 95% confidence interval = 0.600-0.782, P < .001). The N/L ratio may be a useful index of BD activity.

Abstract
We evaluated the efficacy and tolerability of antibiotic regimens and optimal duration of therapy in complicated and uncomplicated forms of spinal brucellosis. This is a multicentre, retrospective and comparative study involving a total of 293 patients with spinal brucellosis from 19 health institutions. Comparison of complicated and uncomplicated spinal brucellosis was statistically analysed. Complicated spinal brucellosis was diagnosed in 78 (26.6%) of our patients. Clinical presentation was found to be significantly more acute, with fever and weight loss, in patients in the complicated group. They had significantly higher leukocyte and platelet counts, erythrocyte sedimentation rates and C-reactive protein levels, and lower haemoglobulin levels. The involvement of the thoracic spine was significantly more frequent in complicated cases. Spondylodiscitis was complicated, with paravertebral abscess in 38 (13.0%), prevertebral abscess in 13 (4.4%), epidural abscess in 30 (10.2%), psoas abscess in 10 (3.4%) and radiculitis in 8 (2.7%) patients. The five major combination regimens were: doxycycline 200 mg/day, rifampicin 600 mg/day and streptomycin 1 g/day; doxycycline 200 mg/day, rifampicin 600 mg/day and gentamicin 5 mg/kg; doxycycline 200 mg/day and rifampicin 600 mg/day; doxycycline 200 mg/day and streptomycin 1 g/day; and doxycycline 200 mg/day, rifampicin 600 mg/day and ciprofloxacin 1 g/day. There were no significant therapeutic differences between these antibiotic groups; the results were similar regarding the complicated and uncomplicated groups. Patients were mostly treated with doxycycline and rifampicin with or without an aminoglycoside. In the former subgroup, complicated cases received antibiotics for a longer duration than uncomplicated cases. Early recognition of complicated cases is critical in preventing devastating complications. Antimicrobial treatment should be prolonged in complicated spinal brucellosis in particular.

Abstract
OBJECTIVE Disability is one of the significant problems that the public faces as regards social aspects, economics, public health and politics. Our aim was to review the prevalence of diseases causing disabilities in young adult men who are declared "unfit for military service" in Turkey after medical examination. METHODS We reviewed the prevalence of diseases among 113,175 young adult men who were referred for medical examination between 2009 and 2011. RESULTS Prevalence of unfitness for military service was 5.56% in 2009, 6.74% in 2010 and 6.77% in 2011. Leading causes for young adult men to be rejected from military service was intellectual disability 6.88, hearing loss 3.71, epilepsy 1.59, schizophrenia 1.54 and diabetes mellitus 1.47 per thousand people. CONCLUSION Screening for the prevalence of disability conditions is an important data source for policies to be developed. Supporting such survey with community based studies in different populations in future shall be beneficial for improvement of policies in social and health fields.

Abstract
e15623 Background: Testicular cancer is a chemosensitive tumor that may be curable even in relapsed disease. Those patients who do not respond to standard combination chemotherapy or relaps may be treated with high-dose chemotherapy (HDC) with autologous stem cell transplantation (ASCT) as salvage therapy. Methods: Eighty five patients that received HDC and ASCT between Feb 1993 - Dec 2012 in different university clinics of Turkey were retrospectively reviewed and evaluated. Results: Median age of the patients was 24 (range: 11-54 years) and 63 patients (74,1%) had stage III, 21 (24,7%) had stage II disease at initial diagnosis. The primary tumor location was testis in 71 patients (83,5%), and 14 patients (16,5%) had extragonadal region origin. Evaluation of metastatic focuses before HDC and ASCT was as follows: Liver metastasis (n = 23, 27.05%), lung involvement (n = 23, 27.05%) and multiorgan involvement (n =14, 16.47%) and other metastatic involvements (n=4, 4.7%). ICE (ifosfamide, carboplatin, etoposide) regimen was performed as HDC in all patients. Median follow-up was 59 (range: 8-218) months. Pre-ASCT patients’ condition was complete remission (n=28, 32.9%), partial remission (n=36, 42.4%) and never in CR (n=21, 24.7%) respectively. 32 patients (37.6%) relapsed or progressed within 1 year after HDC and ASCT median relaps was time 3 months (range: 0.3 - 36.13). Transplant related mortality was %3.5 and 3 patients died within the engraftment period after HDC. Five-year overall survival rate was 59.7%. Conclusions: HDC and ASCT is an effective and safe approach for patients with metastatic and refractory germ cell testicular cancer patients that do not respond to standard combination chemotherapy.

Abstract
BACKGROUND Severe community-acquired pneumonia (SCAP) is a fatal disease. This study was conducted to describe an outcome analysis of the intensive care units (ICUs) of Turkey. METHODS This study evaluated SCAP cases hospitalized in the ICUs of 19 different hospitals between October 2008 and January 2011. The cases of 413 patients admitted to the ICUs were retrospectively analyzed. RESULTS Overall 413 patients were included in the study and 129 (31.2%) died. It was found that bilateral pulmonary involvement (odds ratio (OR) 2.5, 95% confidence interval (CI) 1.1-5.7) and CAP PIRO score (OR 2, 95% CI 1.3-2.9) were independent risk factors for a higher in-ICU mortality, while arterial hypertension (OR 0.3, 95% CI 0.1-0.9) and the application of non-invasive ventilation (OR 0.2, 95% CI 0.1-0.5) decreased mortality. No culture of any kind was obtained for 90 (22%) patients during the entire course of the hospitalization. Blood, bronchoalveolar lavage, and non-bronchoscopic lavage cultures yielded enteric Gram-negatives (n=12), followed by Staphylococcus aureus (n=10), pneumococci (n=6), and Pseudomonas aeruginosa (n=6). For 22% of the patients, none of the culture methods were applied. CONCLUSIONS SCAP requiring ICU admission is associated with considerable mortality for ICU patients. Increased awareness appears essential for the microbiological diagnosis of this disease.

Abstract
OBJECTIVE Youth is a period during which individuals undergo rapid physical and psychological changes in their transition from childhood to adulthood. This study aimed to determine the psychological problems of young males from different socio-cultural backgrounds living in different cities of Turkey and to examine the socio-cultural factors possibly associated with these problems. METHODS The study was conducted in six different cities in Turkey with the participation of 3655 young male adults. Participants were administered a questionnaire to collect socio-demographic data such as age, marital status, educational background, the history of smoking and alcohol use, income level, occupation, place of residence and the history of chronic disease and allergies. Psychological symptoms were detected via the Symptom Check List (SCL-90 R). The study data were transferred to the SPSS-15 database for statistical analysis. RESULTS The median age of the participants was 20.49±1.48years (20-29 age range, median age=20). Based on the SCL-90 R scores, the mean General Symptom Index (GSI) score of the study participants was found to be 0.44±0.27 (0.00-2.61). 13.5% of the participants (n=493) were recorded to have above-the-average GSI scores (≥1.0). Occupation, smoking and alcohol use were found to effect depression. Factors effecting anxiety were occupation, smoking, alcohol use and place of residence. CONCLUSION Psychological symptoms that young people suffer from can be diagnosed at early stages and the psychological problems that are triggered by these symptoms can be prevented with the help of such questionnaires. These questionnaires can easily be administered in primary care settings.

Abstract
BACKGROUND/AIMS The role of chronic kidney disease-mineral bone disorder (CKD-MBD) reversibility in the amelioration of vascular function and in the reduction of the risk for cardiovascular events after renal transplantation is still unknown. METHODS We investigated the longitudinal relationship between the main biomarkers of CKD-MBD and the evolution of vascular function [flow-mediated dilatation (FMD)] after transplantation in a series of 161 patients with kidney failure maintained on chronic dialysis (5D-CKD). RESULTS Before transplantation, FMD in patients was markedly lower (-40%, p < 0.001) than in well-matched healthy subjects and increased by 27% after transplantation (p = 0.001). Fibroblast growth factor 23 (FGF23), 25-hydroxy-vitamin D (25OHVD) and serum phosphate (p < 0.01) were independently associated with simultaneous changes in FMD. Changes in classical risk factors and in risk factors related to CKD like the glomerular filtration rate, serum albumin, C-reactive protein and insulin resistance failed to independently explain the variability in FMD changes after transplantation. CONCLUSION Endothelium-dependent vasodilatation improves after kidney transplantation, which is parallel to the dramatic fall in FGF23, the reduction in serum phosphorus and the increase in 25OHVD levels. If these associations are causal, a part of decline in cardiovascular risk after transplantation is related to partial resolution of CKD-MBD.

Abstract
Neutrophils and lymphocytes (N/L) ratio and carotid intima–media thickness (C-IMT) value have been studied as new predictors of cardiovascular risk. We aimed to investigate N/L ratio and C-IMT value in patients with cardiac syndrome X (CSX) and compare patients with coronary artery disease (CAD) and normal participants. A total of 288 participants were enrolled in the study. The N/L ratio and C-IMT value were compared among the 3 groups. There were no statistically significant differences in N/L levels between CSX and CAD groups. The N/L ratio was found significantly increased in patients with CSX and CAD, compared to the control group. Patients with CAD and CSX had significantly higher C-IMT value compared to control participants. Significant positive correlation was found between C-IMT value and plasma level of N/L ratio. The relationship among CSX and higher N/L ratio level and C-IMT suggests that endothelial dysfunction may contribute to the etiopathogenesis of the CSX.

Abstract
Pentraxin 3 (PTX3) is a new candidate immunoinflammatory marker that has been reported to be associated with cardiometabolic risk factors. We aimed to investigate the effects of valsartan and amlodipine on the PTX3 and C-reactive protein (CRP) levels in patients with essential hypertension. Patients with a newly diagnosed essential hypertension were admitted to our internal medicine outpatient clinic. Patients were randomized to one of the following intervention protocols: calcium channel blocker (amlodipine, 5-10 mg/day) as group A (n = 22; mean age ± standard deviation [SD]: 52 ± 11 year) and angiotensine II receptor blocker (valsartan, 80-320 mg/day) as group B (n = 28; mean age ± SD: 50 ± 14 year). Endothelial dysfunction and systemic inflammation were evaluated with PTX3 and CRP. There was a significant decrease in the level of PTX3 after treatment in two groups (P < .05). Although there was a significant decrease in the level of CRP after treatment in amlodipine group, there was no significant decrease in the levels of PTX3 and CRP after treatment in two groups. There were no significant differences in the systolic and diastolic blood pressure reduction between the two treatment groups. In the treatment of hypertension, prior knowledge of the level of plasma PTX3 could be important in antihypertensive drug choice. C-reactive protein and PTX3 are the markers that have role in vascular inflammation and are found associated with the prognosis of cardiovascular outcomes in many trials. In our study, PTX and CRP levels were decreased when compared to baseline levels.

Abstract
OBJECTIVES There is a lack of data regarding whether edentulous subjects should remove dentures during spirometric measurements or not. The purpose of this study is to determine influences of complete dentures on spirometric parameters in edentulous subjects. MATERIALS AND METHODS A total of 46 complete denture wearers were included in this study. Respiratory functions of the subjects were evaluated by spirometric tests that were performed in four different oral conditions: without dentures (WOD), with dentures, lower denture only and upper denture only. Forced vital capacity (FVC), peak expiratory flow, forced expiratory volume in 1 s and forced expiratory flow between 25% and 75% were evaluated. The data were analyzed with Friedman, Wilcoxon and paired-samples t tests (α = 0.05). RESULTS Significant differences were found between spirometric parameters in different oral conditions (p < 0.05). In all spirometric parameters, the most important significant differences were found between conditions WOD, FVC and with lower dentures (FVC), and WOD (forced expiratory volume in 1 s) and with upper dentures (forced expiratory volume in 1 s) (p < 0.001). CONCLUSION It was observed that complete dentures may unfavourably affect spirometric values of edentulous subjects. However, current findings need to be confirmed with advanced respiratory function tests.

Abstract
PURPOSE To determine circulating levels of the soluble TNF-like weak inducer of apoptosis (sTWEAK)and its association with demographic and biochemical parameters in a young group of patients with newly diagnosed and never treated hypertension. METHODS A total of 51 patients (mean age 21.7 ±1.4 years, body mass index (BMI) 24.5 ±1.6 kg/m2) with primary untreated hypertension, and 37 age- and BMI-matched healthy controls (mean age 22.5 ± 1.9 years, BMI 24.7 ± 1.5 kg/m2) were studied. Serums TWEAK and plasma asymmetrical dimethyl arginine (ADMA) levels were measured by EIA. RESULTS In patients and controls, mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 149.8±5.65/93.4±3.4 mmHg and 124.2±6.4/78.24±5.5 mmHg, respectively. Serum sTWEAK levels were lower in the patient group (882.6±228.9 μmol/L vs. 1060.2±231.7μmol/L, p=0.001), whereas plasma ADMA levels were higher(0.837±0.34μmol/L vs.0.3176±0.25μmol/L, p < 0.001). sTWEAK serum levels correlated with SBP(r=-0.301; p=0.005) and DBP (r=-0.279; p=0.009). Circulating plasma ADMA levels also correlated with SBP (r=0.734; p < 0.001) and DBP (r=0.733; p < 0.001). CONCLUSION Young patients with yet untreated primary hypertension have lower circulating serum sTWEAK level compared with healthy controls. Further research for possible associations among serum sTWEAK, endothelial dysfunction and other measures of atherosclerosis may be of benefit in order to better understand the pathophysiology of hypertension and to establish more effective treatment options.

Abstract
BACKGROUND In this study, we aimed to investigate the protective effects of melatonin (MEL) and S-methylisothiourea (SMT) on mechlorethamine (MEC) induced nephrotoxicity. MATERIALS AND METHODS A total of 36 male Sprague-Dawley rats were divided into four groups: control, MEC, MEC+MEL, and MEC+SMT. Three groups received single dose of MEC (3.5 mg/kg) via transdermal route. Control animals were given saline only via transdermal route. MEL (100 mg/kg) was administered intraperitoneally 30 min after the application of MEC, and after the same dose of MEL was given every 12 h for a total of six doses. SMT (50 mg/kg) was also given intraperitoneally 30 min after the application of MEC. RESULTS The tissue TNF-α, IL-1β, and NOx levels were found significantly different for all groups (P < 0.001). MEC application resulted in severe histopathological changes. Melatonin showed meaningful protection against kidney damage. But protection by SMT was weaker. TNF-α and IL-1β levels increased significantly with MEC application, and MEL and SMT ameliorated these increases in kidney tissue. MEC also elevated NOx levels in kidney tissue. CONCLUSIONS Both inflammation and oxidative stress may have an important role in the MEC induced nephrotoxicity. MEL and SMT may also have anti-inflammatory properties, as well as anti-oxidant properties.

Abstract
OBJECTIVE Overdose of acetaminophen (APAP) can lead to severe liver injury in humans and experimental animals. Pentraxin-3 (PTX-3) is produced and released by several cell types. In this study, we aimed to evaluate whether PTX-3 is a potential biomarker in the identification of APAP-induced liver injury. MATERIALS AND METHODS Thirty adult male Wistar rats were randomly divided into three groups: control, APAP-1 and APAP-2 groups. APAP-1 (1 g/kg) and APAP-2 (2 g/kg) group rats were given APAP by gastric tube. Liver tissues and blood samples were obtained for biochemical and histopathological analysis. Biochemical parameters, plasma and liver PTX-3 levels and degree of liver necrosis were measured in all groups. RESULTS APAP treatments caused necrosis in liver and accompanied by elevated liver PTX-3 levels after 48 h. In APAP-1 and APAP-2 groups when compared with control group (7.5±3.3 ng/mg protein), mean liver PTX-3 concentrations were 14.1±3.0 (p=0.032) and 28.5±8.2 (p<0.001) ng/mg protein, respectively. All rats (100%) in the APAP-2 group had the degree 3 liver necrosis. However 10%, 40% and 50% of rats had the degree 1, the degree 2 and the degree 3 liver necrosis in the APAP-1 group, respectively. The degrees of liver necrosis of the APAP-1 and APAP-2 groups were higher than the group of control (p<0.001 and p<0.001, respectively). CONCLUSIONS PTX-3 may have a role in the APAP-induced liver injury in the rats. The elevated liver PTX-3 in the APAP-induced hepatic necrosis might be a marker of acute histological liver damage. Further prospective studies are necessary to clarify the prognostic value of liver PTX-3 for prediction of histological hepatic necrosis in the APAP-induced liver injury.

Abstract
INTRODUCTION It has been demonstrated that peroxynitrite accompanies acute renal ischemia and contributes to the pathophysiology of renal damage. Therefore, we aimed to investigate the roles of N-acetylcysteine (NAC), a well-known powerful antioxidant, and ebselen (E), a scavenger of peroxynitrite, on renal injury induced by renal ischemia/reperfusion injury (IRI) of rat kidney. MATERIALS AND METHODS Forty male Sprague-Dawley rats were divided into five groups: sham, renal IRI, renal IRI+NAC, renal IRI+E, and renal IRI+NAC+E. IR injury was induced by 60 min of bilateral renal ischemia followed by 6 h of reperfusion. After reperfusion, kidneys and blood samples were obtained for histopathological and biochemical evaluations. RESULTS Renal IR resulted in increased malondialdehyde and nitrite/nitrate levels suggesting increased lipid peroxidation and peroxynitrite production and decreased superoxide dismutase and glutathione peroxidase activities. Both NAC and E alone significantly decreased malondialdehyde and nitrite/nitrate levels and increased superoxide dismutase and glutathione peroxidase activities. Additionally in the renal IRI+NAC+E group, all biochemical results were quite close to those of sham group. Histopathologically, the kidney injury in rats treated with combination of NAC and E was found significantly less than the other groups. CONCLUSIONS Both NAC and E are able to ameliorate IRI of the kidney by decreasing oxidative and nitrosative stresses and increasing free radical scavenger properties. Additionally, combination of NAC and E prevents kidney damage more than when each drug is used alone, suggesting that scavenging peroxynitrite nearby antioxidant activity is important in preventing renal IRI.
